POWDER-DIVIDER.

SPECIFICATION forming part of Letters Patent No. 526,728, dated October2, 1894.

f Application tiled September Z5, 1893. Serial No. 486,480. (No model.)

T0 @ZZ whom it may concern,.-

Be it known that I, ROBERT E. MoCLEL- LAND, a citizen of the UnitedStates, residing at Williamsville, in the county of Sangamon and Stateof Illinois, have invented a new and useful Improvement inPowder-Dividers, of which the following is a specification.

The object of my invention is to provide a` way by which an apothecarymay easily and accurately divide an amount of powder when compounded,into any number of powders of equal size, as for medicines. This I dowith the instrument shown in the drawings, in which- Figure l is a crosssectional view of the lnstrument. Fig. 2 is an end view. Fig. 3 is a topview. Fig. 4 is a side view, and Fig. 5 1s a view of the leveler D D.

Like letters refer to like parts throughout the several figures. A islthe box or body of the instrument and 1n section is made in the form ofan angle as shown in Fig. l. It is closed at one end and 1s open at theother except that a bar runs across the upper part of that end and thepowders are discharged from there in operating the instrument. On oneside of A as shown in Fig. 3 is made a series of notches a a a, therebeing about thirty of thesein the lnstrument. By these notchesregularity in the dividing of powders is secured.

B is a divider the lower part of which has the form of A so that it fitsexactly into A.

B is attached to the sleeve b and revolves about the rod E as an axis.The sleeve b is loose enough to allow a lateral movement along the rod Eso that B may be set down at any position inA as use may require.

C is a stop and is attached to a sleeve c similar to the sleeve b of thedivider B, which moves on the rod E both as an axis and laterally. Theupper arm c of C operates in the notches a a a, and when in the bottomof a stops the divider B so that B can pass no farther to the left tillC is moved. The sleeve b of B and the sleeve c of C are cut on anincllne on their adjoining ends as shown in Figs. 3 and 4 and are out toexactly tit one another when in the positions shown in Fig. l. When thefarther end of B is lifted up by movement on its axis B may passuninterruptedly in A. As it is moved on the rod E the end of the sleeveZ9 strikes against the end of the sleeve c, the sides next to A strikingiirst together because of the position of B, and thus throws the sleevec and stop O into a position corresponding to the position of B. In thiscircular movement of C the arm c is thrown out of notch a thus allowingboth C and B to slip to the next notch a. The spring c3 on the arm c2presses against the side of A as shown in Fig. l and resists thecircular motion of C, and as soon as C is relieved of the firm pressureof B as when rst struck, it throws c back into the next notch a thussecurely stopping B from passing to the left more than the distance ofone notch at a time.

The leveler shown in Fig. 5 is composed of the two pieces D and D. Theyare bound loosely together by clasps at their ends which allow each toslide on the other. The object of the ieveler is to reduce the amount ofpowder placed in the body of the instrument, to the same levelthroughout so that an equal amount will be found in the space covered byeach of the notches a a a( By the movement of D and D on each other theleveler may be adjusted to the width to suit the amount of powder at anytime placed in the body of the instrument.

By using both sides of D D any adjustment may be had from a very smallamount of powder to an amount equal to the capacity of A. When thepowder is properly leveled the divider B is then used and the wholeamount divided into the number of powders desired.

Having thusdescribed my invention, what I claim as new, and desire tosecure by Letters Patent, is y l. In a powder divider the combination ofthe body A in which powders are placed and which has one side notched asat a a a, Withthe rod E fixed parallel to the sides of A, and thedivider B moving on the rod E both as an axis and laterally, and thestop C having the arm c and spring c3, the arm c acting in notches a a.a said stop moving on the rod E the same as divider B and beingcontrolled in its move- IOO ments on rod E by the movement of divider D'on each other the side in A will pass to B and the action of the springo3, substanjust such .depth in A as is desired by the I5 tially as andfor the purposes set forth. operator', substantially as shown and setforth.

2. In a powder divider, the leveler D D in 5 which the parts D and Dlhave their lsides ROBERT E MCCLELLAND' angular-shaped so that theangular surfaces Witnesses: will fit against the sides of the body Awhen S. A. BULLARD, placed in A; and by the movement 0f D and EDWD.FURROW.
